Hi:
I have a portable CD player which requires a 4.5 v. dc source. There are two 1.5 v. batteries which power the unit. Since I can plug in 4.5 volts, I imagine that it is further reduced by diodes which is still a regulated power source. I thought of adding a resistor to a 5v adapter but it would be unregulated causing some problems in the player. My question is: Can I use a 5v dc adapter which I have plenty? We are looking at a .5 v difference. Can that pose a problem? Thanks for y our response?
